Linux – GlusterFS v3.10 not mounting on boot Centos 7.3-1611

FIXED for me at least. And I have no idea how. I've run through the logs from when it wasn't working to now when it is and I cannot for the life of my see any different. What is different and I don't know if it's a coincidence is when I execute

gluster volume status

On both nodes they both say Task Status of Volume glustervol1 where as before in server2 it was the hostname of the box. I have no idea how that happened. But it did… Don't know if that fixed it or what but it did it on it's own after numerous reboots.

Good luck.

STILL?! There's a lot of writing on this from 2014 ish on ubuntu and 14.04 using init. I'm running centos 7.3-1611 fully patched with kernel 3.10.0-514.10.2.el7, and gluster volumes still don't mount after reboot on servers where the lvm bricks and the client vol mount are on the same server.

I have 3 boxes

• server1 (server peer1) and client
• server2: (server peer2) and client
• server3: client only

They are using lvm backend. And the glustervol should mount to /data/glusterfs. The issue isn't present on server3 where it's only a client. It connects and mounts using the same rules as the other servers. I've dug into the data logs, into selinux into the start up log. I can't find a way around it. I've considered CTBD and tried autofs to no avail.

fstab


/dev/vg_gluster/brick1 /data/bricks/brick1 xfs defaults 0 0
gluster1:/glustervol1 /data/glusterfs glusterfs defaults,_netdev 0 0


What's expected


sdb LVM2_member 6QrvQI-v5L9-bds3-BUn0-ySdB-hDmz-nVojpX
└─vg_gluster-brick1 xfs d181747c-8ed3-430c-bd1c-0b7968666dfe /data/bricks/brick1
and
gluster1:/glustervol1 49G 33M 49G 1% /data/glusterfs


This works by running the manual mount -t glusterfs... or by executing mount -a with the rules in my fstab. But it will not work on boot. I've read that it's something to do with the mounts trying to happen before the daemon started. What is the best workaround for this? Is it to edit systemd files? Does anyone know a fix?

This is a snippet of a fresh boot while trying to mount through fstab where it's saying that there is no brick process running.
